BLIND-STOP.

SPECIFICATION forming part of Letters Patent No. 379,120, dated March 6, 1888.

Application filed December 28, 1887. Serial No. 259,215. (No model.)

I citizen of the United States, residing at Alton,

in the county of Madison and State of Illinois, haveinvented certain new and useful Improvements in Stops for Inside Blinds, of which the following is a full and clear description, reference being had to the accompanying drawings, forming a part of this specification, in

which Figure 1 represents an inside bl-indhaving my im'proved'stop applied thereto. Fig. 2 is a perspective view of the stop.

My invention relates to means for adjusting the slats of blinds and of holding the slats in their adjusted positions; and my invention consists in the improved blind-stop, herein after described and claimed.

To enable others skilled in the art to make and use my invention, I will now describe the manner in which I carry the same out.

In the said drawings, A represents a blind of any well-known construction, having the usualpivoted slats, a, and the vertical bar b, to which said slats are connected. To the lower rail, 0, of the blind is pivotally-secnred thelower end of a plate, 13, having its upper or free end provided with a flange, C, at right angles to the body of the plate, and provided with a series of step-like projections, d, upon which the vertical bar I) of the blind is supported. The flange G at the uppermost step also projects slightly beyond the body of the plate, as shown at e, and the lower rail of the blind is provided with a curved slot or groove, f, struck from the pivotal center of the plate, and into this groove or slot the projection 6 passes when the plate B is thrown down out of engagement with the vertical bar I). The lower end of the curved slot therefore serves as a stop for the plate, and yet holds said plate in a position where it may be readily moved up under the bar I).

From this description it will be seen that when increased light or ventilation is desired 1 the pivoted plate is adjusted so that the bar 6 may rest upon either of the lowerstepsorprojections; but if it be desired to shut out the light from the room or reduce the volume of air passing thereto the plate is adjusted until the uppermost step is brought under the bar I). In thislatter position theslats will not only be closed against each other, but the whole series of slats will be held in alocked position by the plate or bar. that I am enabled to regulate the amount of light or air passing into a room by the simple adjustment of the plate B, and at the same time said plate holds the slats in their adjusted positions against accidental displacement.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a blind having pivoted slats and a connecting-bar, of apivoted plate having a series of step-like formations upon which said bar is supported, whereby the slats are adjusted, substantially as herein described.

,2. The blind having pivoted slat-s, a connecting-bar, and a lower rail having a curved groove or slot, in combination with a pivoted plate having step-like formations upon its upper end and a flange, 6, adapted to engage the armed groove or slotin the lower rail,substantially as and for the purpose set forth.
